| Abstract: | From the perspective of adsorption kinetics, factors concerning the reaction order, preexponential factor and the activation energy of flyash＇s adsorption of phosphorus in municipal sewage were all put under examination. The results showed that the reaction order was --0. 0808, the apparent activation energy --25.45kJ/mol and preexponential factor 8. 87 10^-12 （mol L-1 ）^1.0808 min-1. |
